I'm sleepy

Have any of you people ever been so sleepy, but simply cannot go to sleep because you keep on thinking about someone. That is how i feel right now. I have to wake up in a couple of hours, which kinda sucks. I keep on thinking.... and in the back of my head the Shania Twain song called "You're still the one" is playing over and over. Yeah sounds cheesy, and i have a cheesy smile on my face.
